LOCATION HAUSTRUP WIEstablished Series
TAXONOMIC CLASS: Loamy, isotic, frigid Humic Lithic Dystrudepts
TYPICAL PEDON: Haustrup silt loam, on a northwest-facing slope of 12 percent, at an elevation of 1,140 feet. (Colors are for moist soil unless otherwise stated.)
A1--0 to 4 inches; very dark gray (10YR 3/1) silt loam, dark grayish brown (10YR 4/2) dry; strong fine granular structure; friable; many very fine, fine, medium and course roots; extremely acid; abrupt smooth boundary.
A2--4 to 16 inches; very dark grayish brown (10YR 3/2) silt loam, brown (10YR 5/3) dry; moderate medium subangular blocky structure; friable; common very fine, fine and medium; 10 percent angular cobbles; very strongly acid; abrupt smooth boundary.
2R--16 inches; basalt bedrock.
TYPE LOCATION: Burnett County, Wisconsin; about 2 miles east and 3 miles south of Trade Lake; located about 230 feet east and 1,850 feet north of the southwest corner of section 36, T. 37 N., R. 18 W.; USGS Trade Lake topographic quadrangle; lat. 45 degrees 38 minutes 51 seconds N. and long. 92 degrees 32 minutes 56 seconds W., NAD 83.
RANGE IN CHARACTERISTICS: Thickness of loess mantle and depth to lithic contact with basalt ranges from 10 to 20 inches. The weighted average of clay content in the particle size control section ranges from 8 to 14 percent. The weighted average content of coarse fragments in the control section ranges from 0 to 10 percent. Gravel content ranges from 0 to 10 percent and cobble content range from 0 to 10 percent throughout. Volume of stones range from 0 to 5 percent throughout. Reaction ranges from extremely acid to moderately acid throughout.
The Oi horizon (where present) has hue of 7.5YR, value of 3 and chroma of 2 or 3. It is slightly decomposed plant material from a mat of decomposed forest leaf litter.
The A1, A2 or A3 horizons (where present) have hue of 7.5YR or 10YR, value of 2 or 3 and chroma of 1 to 3. It is silt loam.
The R horizon is basalt bedrock.
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING:
Parent material--loess over basalt bedrock
Landform--bedrock controlled uplands
Slope--1 to 25 percent
Elevation--930 to 1,500 feet
Mean annual air temperature--39 to 45 degrees F.
Mean annual precipitation--28 to 33 inches
Frost-free period--100 to 130 days
GEOGRAPHICALLY ASSOCIATED SOILS: This is the Lundeen soil. The well drained Lundeen soil is on a similar landscape position but it is moderately deep to bedrock.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained. Surface runoff is medium to high. Permeability is moderate
USE AND VEGETATION: These soils are used for woodland. Native vegetation is mixed deciduous and coniferous forest. Common trees are northern white cedar, quaking aspen, red oak, white oak and American hornbeam.
DISTRIBUTION AND EXTENT: Northwestern Wisconsin. LRR K, MLRA 90A. This soil is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota.
SERIES ESTABLISHED: Burnett County, Wisconsin, 2003. The source of the name of this series is Haustrup road in Burnett County.
REMARKS: Diagnostic horizons and features for this pedon include:
Umbric epipedon: 0 to 16 inches (A horizon).
